Those holding Pinlive Foods Co., Ltd. (SZSE:300892) shares would be relieved that the share price has rebounded 30% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 31% in the last twelve months.

Even after such a large jump in price, it's still not a stretch to say that Pinlive Foods' price-to-sales (or "P/S") ratio of 1.4x right now seems quite "middle-of-the-road" compared to the Food industry in China, where the median P/S ratio is around 1.7x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

How Has Pinlive Foods Performed Recently?

As an illustration, revenue has deteriorated at Pinlive Foods over the last year, which is not ideal at all. It might be that many expect the company to put the disappointing revenue performance behind them over the coming period, which has kept the P/S from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

What Are Revenue Growth Metrics Telling Us About The P/S?

There's an inherent assumption that a company should be matching the industry for P/S ratios like Pinlive Foods' to be considered reasonable.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 27%. The last three years don't look nice either as the company has shrunk revenue by 19% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 16% shows it's an unpleasant look.

With this information, we find it concerning that Pinlive Foods is trading at a fairly similar P/S compared to the industry. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh on the share price eventually.

What We Can Learn From Pinlive Foods' P/S?

Its shares have lifted substantially and now Pinlive Foods' P/S is back within range of the industry median. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

The fact that Pinlive Foods currently trades at a P/S on par with the rest of the industry is surprising to us since its recent revenues have been in decline over the medium-term, all while the industry is set to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
